This is a free 3D laser cut pendant lamp built from 14 flat parts, drawn for 3 mm sheet material. Assembled, the shade stands 34.6 cm tall with a diameter of 17.6 cm, giving it the scale of a physical pendant shade. The files are supplied for laser cutting workflows in DXF, SVG, CDR, DWG, and PDF.
Laser Cut Pendant Lamp Design and Light Pattern
We designed this lamp around the light it casts, not only around how the panels look flat on the sheet. The body is a cylinder of twelve vertical side panels, eight wider and four narrower, that close into a continuous ring. Each panel carries a flowing wave opening running down its length. Those waves are the point: with the bulb inside the cylinder, the light has to pass through the curved wall, and the wave openings shape how it spreads into the room. We drew them as smooth, continuous curves so the cut edge follows the wave cleanly and the light pattern stays soft rather than broken up.
The top is a circular plate cut with a sun-like radial pattern around a center hole. We gave it that pattern for a reason beyond holding the lamp together. The radial slots let light escape upward, so the fixture can throw a second, softer glow onto the ceiling while the side waves light the space around it. The design work was in balancing those two effects: the side waves carrying light outward and the radial top pattern letting a softer glow move upward.
The fourteenth piece is a lower inner support ring. It sits inside the lower body and keeps the panels aligned and evenly spaced around the base, so the cylinder holds its round shape down its full height. It is an internal aligning ring, not a closed bottom, so the underside of the shade stays open and the bulb stays reachable. Each side panel also keeps a continuous solid border around its wave openings, so no panel is cut so far that it loses its own frame. Between the radial top plate squaring the upper edge and the support ring bracing the base, the body is designed to stay supported at both ends.
The slots are drawn as pure nominal geometry. A 3 mm slot in the file is mathematically 3.000 mm, with no fit tolerance built in, because the seating tightness belongs to your workshop, not to the drawing. Your sheet, your machine, and your software decide the final fit, which leads into the cutting notes below.
Cutting Notes for 3 mm Sheet Material
The file gives you nominal drawing geometry. Matching it to your real material and machine is the part you control, and it is worth a few minutes before you commit a full sheet. Measure your actual sheet with calipers, since real 3 mm stock drifts with humidity, temperature, manufacturer, and quality. Then measure your own laser kerf, and use your measured kerf and sheet thickness to set the appropriate kerf compensation, offset, or slot adjustment in your cutting software, for example in LightBurn under Cut Settings, Advanced, Kerf Compensation. That is how the exact file geometry is physically adjusted to your machine and your sheet.
A few practical notes before cutting:
- Drawn as nominal geometry, with 3 mm slots and no built-in fit tolerance
- Measure your actual sheet thickness with calipers
- Measure kerf on a test cut and set kerf compensation, offset, or slot adjustment in your software
- Suitable materials can include wood sheet, plywood, MDF, or acrylic
- Use suitable LED lighting hardware
